Why do curls lose definition in humid climates?
Curls soften in humidity due to water molecules disrupting temporary hydrogen bonds and causing uneven swelling of internal hair components.

How does hair absorb moisture?
Hair absorbs moisture through its cuticle and cortex, primarily via hydrogen bonds with keratin proteins, with porosity and lipid content shaping its hydration.

Genetic Variants
Meaning ❉ Genetic variants are the subtle, inherited DNA differences that define the unique curl, strength, and characteristics of textured hair.

Curl Pattern Biology
Meaning ❉ Curl pattern biology unveils the profound science behind hair's inherent curves, from genetic blueprints to cultural narratives.

What molecular differences account for textured hair characteristics?
Textured hair characteristics stem from elliptical follicles, asymmetrical keratin distribution, higher disulfide bond density, and unique lipid profiles.

How do genetics shape hair curl?
Hair curl is primarily shaped by the inherited elliptical or S-shape of hair follicles and the asymmetrical distribution of keratin proteins within the hair shaft.

How do internal structures influence curl?
Hair's internal structures, including follicle shape, protein distribution, and genetic variations, fundamentally dictate its curl pattern.
